What is the vapor pressure of the pure solvent if the vapor pressure of a solution of 15g sucrose (C12H22O11) in 100g of ethanol (C2H5OH) is 58 mmHg?
5 mL of nitric acid, HNO3, are required to react with 50 mL of a 1.25 M Barium hydroxide, Ba(OH)2 solution:
2 HNO3 (aq) + Ba(OH)2 (aq) --> 2 H2O (aq) + Ba(NO3)2 (aq)
Determine the concentration (Molarity) of the nitric acid solution (HNO3).
How many mL of 0.250 M barium nitrate are required to precipitate as barium sulfate all the sulfate ions from 50 mL of 0.350 M aluminum sulfate?
3 Ba(NO3)2 (aq) + Al2(SO4)3 (aq) --> 3 BaSO4 (s) + 2 Al(NO3)3 (aq)
